Tfoiallwhom itmay'concelrow I it known"that]I,[JAoOn 'KNA'Pni'a citizen of the United States, residing in Newark, in the c'ounty of Essexf and State of 5 New Jersey,- have inventedrcertain new and useful Improvements in Alcohol Torches,

"of which the following is afispecification. invention [has for its main object to "provide a ortable torch or blow pipe adapted to use liquid fuel,fespec'ially alcohol, capable of delivering a blast of flame of intense heat l laterally of its body without the I use of a pump or other auxiliary means.

. Another object is to produce ajdevice that will operate contin Q ifl iial Position fatter th i i l g liLiQ 15 1 s a y. b required, at; which tinie the flame is readily l'q iich d- 2 p1 I A' further purpose is toprovide' means 7 whereb'y the' flame jina-y be adjustab-ly con- I trolled when operating. I

Still another object is in the pro-vision of ineans for preventing loss of fuel by evapo f QI .1 M I 5 Theseand'snnilar objects aregattained by i'the novelconstruction, combination and arrangement of parts, hereinafter described land shown -in' the accompanying drawings w ,a materlal part of this disclosure,

with parallel front' andj rea'i'f walls and curved sides. I

" V At the center of thefarcnately domed top 11 the material isjformedlinto a c0a'rse pitched Screw threaded nipple 12 to which is; tight fitted a correspondingly threaded cylindrical cap l l'ihaving near-"its upper-end a fixed transvers'efplate l5 7 there being-se .curecl-inthe center of the plate a wickftube. 16,1itslo'wer end extending intoythe; con

cap 14 is also screw-threadedexternally and;

engaged therebyis a band or ring 20 havingfan internalfiange 2l provided with a raised serrated margin22 by whichthe device can be rotated. 1

A cross bar 23 extendsldiainetrically across, the top of the bar beingexpaiided at its center 24 from the under side-of which extends, a rigid conicalprojection 25, in'register with the funnel shaped end l l' of the wick tube, which contains la lwick 26 extend- V ing approximately to the botto'mofthe container. I

Another wick 28 rises from the container i and passes {out joffthe "nipple 12;' over its upper edge in a tube30 fixed toone side of,

the cap 14 and to which it isfully open.

.The tube 30 is bent into a"semi-circle,';the I upper elementof the curve blending into ahorizontal portion 31,;flattened bycoinpressing the wall of the tube *laterally, and,

extended directly ,over, at some distance above, the center of the. tube 16, and ,pfii'os 1 cc The el'emeiitBl Inerge' attitsioppositeiend, 1.

'the*burner tube, which like the oppo sitely curved element .05; Si fixed to the Cap" llfajnd 05a communicates withits'ilint r'io'r byra small opening 35.

30 somewhat past the center of its'curvature, while similarly positioned in the symmetrical opposite side 33 is a filling 36 of some fibrous material, as cotton in its natural condition. V

In operation, the container having been supplied with liquid fuel by removing the cap or through a filling nozzle (not shown) through'the spaces in the flange 21 and impinging on the burner tube element 31.

The element 31 upon becoming heated receives gasesor vapor from the wick 2S and also any that may riseinthe cap and thence conducted by the fiberfilling v36, the combined gases being superheatedby the flame at the top of the cap, which can be controlled by raising or lowering the projection 25, thereby loosening or compressing the wick, increasing or diminishing its carrying capacity, and the flame immediately ignites the gases issuing from the orifice 32.

When the flames are quenched and the burner tube cooled the wicks 26 and 28 filling their respective tubes and the filling 36 covering the opening in the cap, effectually preventing loss of fuel material by evaporation or otherwise, it being possible to invert the torch, whether operating or not without leakage or loss.

From the foregoing it will be seen that a neat appearing and convenient torch has been disclosed fully capable of fulfilling its several objects in an effective manner.

, While certain preferred embodiments of this device have been shown and described, it will be understood that changes in the form, arrangements, proportions, sizes and details-thereof may be made without departing from the scope of the invention as defined in the appended claims.

Having thus described my invention, what I desire to secure by Letters Patent and claim, is V a 1.
